Step-by-step explanation:
The most important single factor to the safe operation of forklifts is the competency of the operator. Much like how the Federal Aviation Administration (FAA) has introduced regulations for pilots, the proper training and adherence to protocols are crucial for forklift operators. Comprehensive training programs ensure that operators are familiar with the equipment and can react appropriately to different situations to minimize the risk of accidents. Other important factors include regular maintenance of the forklift, adherence to safety checklists, and limiting operation hours to prevent operator fatigue.
